So the questions must be asked which RCs ignore:
1. Consistent with your literal interpretation here, no one can have spiritual life in them and eternal if they do not believe in the Catholic real presence, correct ?
2. Where in Scripture (even though that is not your real basis for assurance) did the apostles preach taking part in the Lord's supper in order to gain spiritual life in them? Or where does it show believers being ? Or show souls not being born again, thus having spiritual life in them, until they took part in the Lord's supper?
3. Where in all the aspects which John writes of in 1 John so that souls may know they have eternal life (cf. 5:13) does he teach that receiving the Catholic real presence is that means?
4. Where are the verses in John 6 that you listed infallibly interpreted, or is this something you can disagree refers to the Catholic real presence (i say "Catholic," because evidently it was the Anglicans that first began using the phrase)
Anyone on your list can fill in for you. But if you respond, this time refrain from resorting to your perfunctory images as a substitute for an argument.
Jesus said to them again, Peace be with you. As the Father has sent me, even so I send you. And when he had said this, he breathed on them, and said to them, Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.
